Natural Yellow Cat's Eye Opal 13.50ct Oval Cabochon

An unusual and striking opal that combines the gemstone's natural vitreous sheen with a secondary optical phenomenon - chatoyancy. The stone displays a warm golden-yellow to olive body color with a clean, silky cat's eye line that glides across the surface as the stone tilts, created by parallel fibrous inclusions reflecting light in a focused band. Both under standard and incandescent light the cat's eye remains crisp and well-centered on this large, well-proportioned oval.

From Africa and completely natural, this opaque oval cabochon is a true collector's piece - cat's eye opals are far less common than classic play-of-color varieties. It pairs well with bezel settings and bold statement rings where the full oval face can be displayed and the chatoyant line clearly seen. Untreated.
